|estradiol vaginal ring|
|How does this medication work? What will it do for me?|
Estradiol vaginal ring belongs to the class of medications called local estrogen replacement therapy. It is used for the management of vaginal and urinary menopausal symptoms such as a feeling of dryness in the vagina (with or without itching), painful intercourse, painful urination, or the feeling of needing to urinate more often than usual.
Estrogen is a female hormone that is produced by the ovaries. Once menopause is reached, the ovaries produce less estrogen and symptoms associated with menopause can occur. Estradiol vaginal ring works by providing local-acting estrogen. However, it does not provide enough estrogen to manage other symptoms of menopause such as hot flashes.
Estradiol vaginal ring releases estradiol into the vagina in a consistent, stable manner for 90 days. The full effects of the vaginal ring will not take place for about 2 to 3 weeks. If your symptoms continue beyond this time, you should contact your doctor.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. As well, some forms of this medication may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.
|How should I use this medication?|
The vaginal ring can be placed in the upper third of the vagina by yourself or your doctor and worn there continuously for 90 days. It is then replaced if your treatment is to be continued.
To insert the ring yourself (as agreed upon by you and your doctor):
Most women and their partners experience no discomfort with the vaginal ring in place during intercourse, so it is not necessary that the ring be removed. If the vaginal ring should cause you or your partner any discomfort, you may remove the ring prior to intercourse. To remove the vaginal ring, wash and dry your hands thoroughly. Assume a comfortable position, either standing with one leg up, squatting, or lying down. Loop your finger through the ring and gently pull it out. Rinse the ring with lukewarm water and reinsert it as soon as possible after intercourse.
The vaginal ring may slide down into the lower part of the vagina as a result of the abdominal pressure or straining that sometimes accompanies constipation. If this happens, gently guide the ring back into place with your finger. If the vaginal ring slips out, wash it with lukewarm water and reinsert. If the vaginal ring slips out frequently, contact your doctor.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a different dose than the ones listed here, do not change the way that you are using the medication without consulting your doctor.
It is very important to use this medication exactly as prescribed by your doctor.
Store this medication at room temperature, and keep it out of the reach of children.

|Are there any other precautions or warnings for this medication?|
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Note the following important information about estrogen replacement therapy:
The Women's Health Initiative (WHI) study results indicated an increased risk of heart attack, stroke, breast cancer, blood clots in the lungs, and blood clots in the leg veins in postmenopausal women during 5 years of treatment with 0.625 mg conjugated equine estrogens and 2.5 mg medroxyprogesterone compared to women receiving sugar tablets. Other combinations of estrogen and progestins were not studied. However, until additional data are available, the risks should be assumed to be similar for other hormone replacement products. Therefore,
Blood clotting disorders: Estrogens with or without progestins are associated with an increased risk of blood clots in the lungs and legs. This risk also increases with age, a personal or family history of blood clots, smoking, and obesity. The risk of blood clots is also increased if you are immobilized for prolonged periods and with major surgery. If possible, this medication should be stopped 4 weeks before major surgery. Talk about the risk of blood clots with your doctor.
Blood pressure: Women may experience increased blood pressure when using estrogen replacement therapy. Talk to your doctor about how often you should have your blood pressure checked.
Breast and ovarian cancer: Studies indicate an increased risk of breast and ovarian cancer with the use of combined estrogen and progestin therapy. Women who have a history of breast cancer should not use estrogens. Women with a family history of breast cancer or women with a history of breast lumps, breast biopsies, or abnormal mammograms should be closely monitored by their doctor if they use estrogens. Women should have a mammogram before starting hormone replacement therapy. Women taking estrogens should have regular breast examinations and should be taught how to do a breast self-examination.
Bone disease: If you have bone disease due to cancer or a metabolic condition causing too much calcium in your body, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Dementia: Women over age 65 receiving combined estrogen and progestin replacement therapy may be at increased risk of developing dementia (loss of memory and intellectual function). If you are over 65, talk to your doctor about whether you should be tested for dementia.
Diabetes: If you have diabetes, your doctor should closely monitor your condition while you are taking this medication, as it may affect blood sugar control.
Endometrial cancer: Medications containing estrogen increase the risk of cancer of the endometrium (lining of the uterus) in women who have had menopause. If you use any estrogen-containing medication, it is important to visit your doctor regularly and report any unusual vaginal bleeding right away.
Endometriosis: Estrogen replacement therapy can cause endometriosis to reappear or get worse. If you have or have had endometriosis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Follow-up examinations: It is important to have a follow-up examination 3 to 6 months after starting this medication to assess the response to treatment. Examinations should be done at least once a year after the first one.
Gallbladder: This medication can aggravate gallbladder disease or increase the risk of developing it. If you have gallbladder disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart disease and stroke: Studies indicate an increased risk of heart disease and stroke with estrogen (with or without progestin) for postmenopausal women. If you experience symptoms of a heart attack (chest pain, tightness or pressure, sweating, nausea, feeling of impending doom) or stroke (sudden dizziness, headache, loss of speech, changes in vision, weakness or numbness in the arms and legs) while taking this medication, get immediate medical attention.
Liver disease: If you have liver disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Other medical conditions: Discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed, if you have any of the following conditions:
Vaginal infections: Vaginal infections should be treated by your doctor before starting this medication. If a vaginal infection develops while using estradiol vaginal ring, remove the ring until the infection has cleared, and then re-insert it into the vagina.
X-ray procedures: Remove the vaginal ring before having any X-ray procedures of the lower abdominal tract. Be sure to tell all your doctors that you are using an estrogen vaginal ring.
Pregnancy: Estrogen vaginal ring must not be used during pregnancy. If you become pregnant while using this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking this medication, it may affect your baby. This medication is not recommended for breast-feeding women.
Children: The safety and effectiveness of using this medication have not been established for children. This medication is not intended for use by children.
|What other drugs could interact with this medication?|
There may be an interaction between the estradiol vaginal ring and any of the following:
Estradiol vaginal ring releases small amounts of estrogen locally in the vagina and drug interactions are less likely to occur with the vaginal ring than with estrogen medications taken by mouth.
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.
